Acer pseudosieboldianum
''Acer pseudosieboldianum'', the Korean maple or purplebloom maple, is a species of maple. It is native to northeastern China, Korea, and the Russian Far East.〔Hokanson, S. (''Acer pseudosieboldianum'' - A Japanese-like maple for the North? ) ''Yard & Garden Line News'' 5(15) September 15, 2003. University of Minnesota Extension.〕〔(''Acer pseudosieboldianum''. ) Germplasm Resources Information Network (GRIN).〕
==Description==
''Acer pseudosieboldianum'' is a small tree or shrub. It is deciduous. It grows about 12 to 18 inches per year. The mature tree is 15 to 25 feet tall.〔(Cultural Details for ''Acer pseudosieboldianum''. ) Boone County Arboretum. Union, Kentucky, USA.〕〔(Flora of China, ''Acer pseudosieboldianum'' (Pax) Komarov, 1904. 紫花枫 zi hua feng )〕
The leaves are 4 to 6 inches wide and have usually 9 to 11 lobes. The green leaves turn shades of red, yellow and orange in fall. This species exhibits Marcescence (tends to hold on to a portion of its dried leaves through the winter). The flowers are white with purple bracts. New growth is coated in white, sticky hairs. This characteristic distinguishes the plant from the similar ''Acer sieboldianum'', which lacks hairs.〔(Komarov, Vladimir Leontjevich 1904. Trudy Imperatorskago S.-Peterburgskago Botaničeskago Sada 22: 725-727 ) in Russian〕
The bark of the plant is thin and easily damaged by mechanical injury or in harsh weather. Tears in the bark make it vulnerable to insect and fungal infestation. The species is susceptible to canker and Verticillium wilt when stressed.
